6. INTERPOLATION FUNCTION
255
The G00 command moves a tool to the position in the workpiece system
specified with an absolute or an incremental command at a rapid traverse
rate.
In the absolute command, coordinate value of the end point is
programmed.
In the incremental command the distance the tool moves is programmed.
The tool path is determined by selecting one of the following with
parameter LRP (No. 1401#1):
D Linear interpolation type positioning
The tool is positioned using a straight path and a speed that is not
higher than the rapid traverse of each axis but that assures the shortest
positioning time. By changing the acceleration/deceleration type
from the constant acceleration/deceleration (inclination) type to the
constant time (time constant) type with bit 4 (PRT) of parameter No.
1603, the tool can be moved along a specified path.
D Non–linear interpolation type positioning
Positioning is performed with each axis independently at the rapid
traverse rate. Generally, the tool path is not a straight line.
The rapid traverse rate in the G00 command is set to the parameter
No.1420 for each axis independently by the machine tool builder. In the
positioning mode actuated by G00, the tool is accelerated to a
predetermined speed at the start of a block and is decelerated at the end
of a block. Execution proceeds to the next block after confirming the
in–position.

LRP Positioning (G00)
0 : Positioning is performed with non–linear type positioning so that the
tool moves along each axis independently at rapid traverse.
1 : Positioning is performed with linear interpolation so that the tool
moves in a straight line.
